Agent / AI Engineering · CS @ Guangzhou College of Commerce · Guangzhou
Building AI-native full-stack systems — from Multi-Agent workflows to security-hardened backend migrations.
AI Full-Stack Intern · Baidu (China) Co., Ltd. Guangzhou Branch 2026.07 – 2026.08
Led the security-hardening rewrite of the e.baidu backend system.
- Designed and led a strangler-fig migration from a
ThinkCMF 6 + ThinkPHP 6PHP monolith toNestJS 10 + TypeScript, fixing P0 vulnerabilities (arbitrary SQL execution via WebSocket, hardcoded credentials, superuser hard-bypass) - Implemented zero-trust JWT gateway integration (UUAP), dual-guard RBAC with strict-deny defaults, and hashed sensitive-field indexing
- Migrated 30 read-only API paths / 39 operations with 85 Jest tests passing; shipped a React 18 + Ant Design Pro admin frontend with an SSE-streamed agent chat preview (13 Vitest tests passing)
AI/LLM Engineering Intern · Guangzhou Xin'an Data Co., Ltd. 2026.04 – 2026.07
Built Multi-Agent document review pipelines for enterprise brand & KPI compliance systems.
- Orchestrated multi-node Agent workflows with
Dify, converting manual report review into a fully automated pipeline across 7 intent-routed review dimensions - Optimized RAG retrieval (hierarchical Markdown chunking + Hybrid Search + Reranker on
Milvus) — QA accuracy 60% → 88% - Built a provider-agnostic LLM connection pool with exponential backoff, token-bucket rate limiting, and streaming support
Founder / Full-Stack Developer · Guangzhou BoBaCarry Smart Tech Co., Ltd. 2025.09 – 2026.04
Built a shared smart-follow-cart platform end-to-end, from WeChat Mini Program to production deployment.
Node.js + Expressbackend withMySQL + Redis(<50ms response latency);Vue 3 + Element Plusops console- Defined MQTT device protocol with hardware engineers; built a device simulator to unblock firmware integration before hardware arrived
